I just finished putting my the top end of my engine back together, and to my dismay my poor Hobbit no longer starts. It seems to be a lack of compression.
I had just had my cylinder off and replaced my piston rings, and when I put it back on I torqued the bolts down to 7ft/lb (manual said between 5.6 and 8.7) Thinking maybe the bolts needed a little more torque, I set my wrench to 8ft/lb and started turning each one down in a star pattern.
3 out of 4 bolts clicked, but the top right bolt just kept going. After a couple cranks I start getting nervous - maybe I'm gun shy bc I just broke a bolt off (other side) a few weeks ago and it was agonizing getting it out - so I pull the bolt out to look at it.
In the attached picture #1 is a spare bolt I had laying around, #2 is the bolt I just took out, and #3 is the second bolt I tried next.
To me bolt #2 looks a little fucked up, like the threads were stretching out and it was about to snap. So I take another spare bolt and start torquing down, but that seems like I've turned my wrench way too many times too and so I take that one out too (#3)
Am I crazy? Should I just trust the torque wrench, or is it possible something is wrong with the hole in the case? I'm wondering if this might be the issue with my compression. (edited)
